Dialing Formats and Instructions
For local callers within the United Kingdom, the number is dialed in national format as 01256 XXX XXX (where X represents the local subscriber number, typically 6 digits). When calling from outside the UK, the international format is +44 1256 XXX XXX, dropping the leading zero of the NDC. For example, a local number 456789 would be dialed as 01256 456789 from within the UK, and as +44 1256 456789 from abroad.
Callers from other UK area codes must dial the full national number, including the trunk prefix '0'. No area code overlay is currently in place for Basingstoke, so the 01256 code is used exclusively for geographic numbers in this region.
Caller Instructions
- Local callers: When dialing another number within the same 01256 area, it is still necessary to dial the full 01256 number, as UK numbering does not allow local dialing without the area code.
- International callers: From outside the UK, dial your country's exit code (e.g., 00 from Europe, 011 from the US), followed by 44, then 1256, and the 6-digit subscriber number. Do not include the leading '0'.
Geographic numbers in the UK are traditionally associated with fixed-line PSTN services, but number portability allows them to be redirected to VoIP or mobile services. However, the tariff structure remains that of a geographic call, which may be included in bundled minutes or charged at a standard rate.
